Quantum Threats vs. Blockchain – A New Line Drawn

Major cryptographic breakthrough announced by Sui Research could help blockchains survive the coming quantum era – but Bitcoin and Ethereum are left out.

What happened?

A team led by cryptographer Kostas Chalkias has proposed a backward-compatible, quantum-safe wallet upgrade — no hard forks, no address changes, no key regeneration required.

Works for:

• $SUI

• $SOL

• $NEAR

• $Cosmos

(Any chain using EdDSA)

Doesn’t work for:

• Bitcoin

• Ethereum

(Both still reliant on older cryptographic signatures.)

Why it matters:

Once quantum computers reach “supremacy,” millions of wallets – including Satoshi Nakamoto’s BTC – could be instantly compromised if public keys are visible.

Key Insight:

This solution uses zero-knowledge proofs to validate new quantum-resistant keys without revealing old ones, preserving privacy AND security.

“Millions of dormant wallets could be drained instantly in a post-quantum world,” says Chalkias.

“This is the first real path to upgrade blockchains without breaking them,” adds Dan Dadybayo.

For Bitcoin/Ethereum: A hard fork may be inevitable if they want to remain secure in the quantum era.

TL;DR:

A new cryptographic solution may future-proof next-gen blockchains.. but the original giants might be forced to make the biggest upgrade of their lives.
